This are just the cute warwaras, the look nice on fish tank, you can add LEDs inside… there is both hollow and solid models of most of them

If you add a magnet inside it can be held from metallic objects

I made them in onshape https://cad.onshape.com/documents/2c05f9844a051880fd7e3478/w/a47f926f368d9a10abbfeea2/e/eb1b4579feabc21262511f23?renderMode=0&uiState=65e677b05b5b055ecb01764c

The model is easy to edit so feel free to make your own custom warawara :)

I also made a lmap from them which you can see in my profile
